GeForce RTX 2070 Super vs GeForce RTX 2080

Intro

The GeForce RTX 2070 Super comes with a core clock frequency of 1605 MHz and a GDDR6 memory speed of 14000 MHz. It also features a 256-bit memory bus, and uses a 12 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 ROPs.

Compare all that to the GeForce RTX 2080, which makes use of a 12 nm design. nVidia has set the core speed at 1515 MHz. The GDDR6 RAM is set to run at a speed of 14 MHz on this specific model. It features 2944 SPUs along with 184 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce RTX 2080 is a little bit (approximately 9%) better at anisotropic filtering than the GeForce RTX 2070 Super. (explain)

GeForce RTX 2080 278760 Mtexels/sec
GeForce RTX 2070 Super 256800 Mtexels/sec
Difference: 21960 (9%)

Pixel Rate

The GeForce RTX 2070 Super is a little bit (more or less 6%) better at AA than the GeForce RTX 2080, and able to handle higher screen resolutions while still performing well. (explain)

GeForce RTX 2070 Super 102720 Mpixels/sec
GeForce RTX 2080 96960 Mpixels/sec
Difference: 5760 (6%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
